GPS Accuracy
Differential Correction GPS (DGPS), such as the Wide Area Augmentation

meters. Most developed countries have some type of DGPS. Standard
GPS is available globally, and is accurate to 15 meters (49.2 feet).
Nutrient Tracker Mapping Capability
Nutrient Tracker uses GPS and weight information collected from the NT
460 and creates reports that overlay delivery areas on satellite images for
nutrient management and record keeping. Nutrient Tracker can also export
standard “CSV” and “shape” files for use in other mapping programs.
Note: Mapping requires an internet connection.

Daily Data Collection
DAILY DATA COLLECTION
Insuring your data is secure from theft, fire or equipment failure requires a
small effort each day to store your data on a USB drive.
Indicator Memory
When powering up the NT 460 the memory percent full is shown on the
display. The NT 460 has enough memory to store approximately 400 loads
while sampling every ten seconds and unloading one load every nine
minutes.
It is recommended to download data from the NT 460 to the USB drive
before the memory is close to full. It takes just under five minutes to
download data when the memory is 25% full and under ten minutes when
50% full.
Mid-Season Name Changes
During the season, you may wish to delete and add field names or ID
names to your scale indicator memory. This may be done in one of two
ways.
Front Panel
For a small amount of changes, edit field names and ID names using the
keypad on the front panel. See page 8 and 10 to edit field names and ID

Re-Calibrating your Scale
RE-CALIBRATING YOUR SCALE
To re-calibrate your scale and make it even more accurate, document at
least 3 to 6 loads of varying sizes and measure the actual weight of all
loads on a certified scale.
•
Weigh the load immediately before unloading and immediately
after unloading to minimize errors due to changes in fuel etc.
In this example, we are unloading six carts of nutrient onto four semi-
trucks.
Example:
Weight Scale Weight
Cart Load A 33660 33900
Cart Load B 33240 33540
Cart Load C 35200
Total Weight 102100 102920
Reading Too High
If the Indicator is reading higher than the certified scale, then the
calibration number is high and should be decreased proportionally. See
page 38.
Reading Too Low
If the Indicator is reading lower than the certified scale, then the calibration
number is low and should be increased proportionally. See page 38.
